-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2018:2603-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:2603 Issue date: 2018-08-29 CVE Names: CVE-2018-3620 CVE-2018-3646 ===================================================================== 1. Summary: An update for kernel is now available for Red Hat Enterprise Linux 5.9 Long Life. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Long Life (v. 5.9 server) - i386, noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting these issues. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1585005 - CVE-2018-3620 CVE-2018-3646 Kernel: hw: cpu: L1 terminal fault (L1TF) 6.
